Answer:

Greater

Explanation:

When the Sun and Moon are lined up (at new moon or full moon), the tides produced reinforce each other and are more significant than average (Figure 4). These are called spring tides (the name is connected not to the season but to the idea that higher waves “spring up”).

Alu element at the PV92 locus on Chromosome 16. In this population, 436 people have a heterozygous genotype and 102 people have

Lesechka [4]

Answer:

Explanation:

According to the exercise we can infer that for the Alu insert:

p: positive allelic frequency

q: negative allelic frequency

maintaining that the population is in equilibrium we can carry out the following formula

p + q = 1 and pp + 2pq + qq = 1

looking for the genotype frequency we clear and obtain the following data

genotype frequency of 2pq = 436/1000 = 0.436

The genotype frequency of qq = 102/1000 = 0.102

This is how we look now:

number of positive people for Alu = 1000- (436 + 102) = 1000- 538 = 46

In this way it is resolved that:

genotypic frequency of pp = 462/1000 = 0.462

p = 0.462 + (0.436 / 2) = 0.462 + 0.218 = 0.680

q = 0.102+ (0.436 / 2) = 0.102 + 0.218 = 0.320

According to the exercise carried out it is deduced:

The value of p in the population is = 0.68

We conclude that our prognosis showing a homozygous positive genotype is: 0.462

Give an example of spinal reflex and explain how the nervous system functions in this reflex action

Bad White [126]

The patellar reflex is the most common example or a spinal reflex. When the knee is tapped, the nerve that will receives this stimulus sends an impulse to the spinal cord and relay it to the motor nerve. This sources the quadriceps muscle at the front of the thigh to contract and twitch up the leg. This reflex contains simply two nerves and one synapse. The leg will start to twitch up on the other hand the brain is just suitable aware of the tap and comprehends the situation. <span>Subsequently the tap, the leg is routinely lengthy once and comes to rest. The nonappearance of this reflex is problematical and recognized as westphals sign this reflex might be lessened or absent in lower motor neuron lesions and during sleep. </span>

What is true about the lagging strand during DNA replication?

BlackZzzverrR [31]

There are not only one but two correct option, which are A and B.

DNA polymerases begin their synthesis at many points of initiation. Following the binding of specific proteins, the double helix opens to allow startup.

DNA synthesis begins on RNA / DNA primers consisting of primase and DNA polymerase a. The replication continues in one direction: in this sense one of the two strands of the DNA ("direct" strand) is traversed by the enzyme in the 3 '→ 5' direction, which allows the synthesis of another strand in the direction 5 '→ 3'. The DNA-ligases then provide the link between the different fragments of the new DNA.

The synthesis of the other strand ("delayed" strand) is more complex because the enzyme travels this strand from 5 '→ 3'. The primase and DNA polymerase α synthesize 30 nucleotide primers in front of the replication zone, and the DNA polymerase constructs small DNA fragments in the 5 '→ 3' direction (approximately 200 nucleotides; Okazaki). Ribonucleases destroy the RNA / DNA primers of the previous fragment and the fragments are then linked together by DNA ligase.
